[Docket No. FAA-2015-0081; Directorate Identifier 2014-NM-170-AD]
RIN 2120-AA64

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. 
This proposed AD was prompted by reports of fluid entry and 
accumulation in the aft equipment bay. This proposed AD would require 
modifying the aft equipment bay. We are proposing this AD to prevent 
excessive quantities of flammable fluid accumulation in the aft 
equipment bay. Flammable fluid entry and accumulation in the aft 
equipment bay, in excessive quantities, could exceed safe levels 
maintained by the drainage and ventilation system.

DATES: We must receive comments on this proposed AD by March 12, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    Transport Canada Civil Aviation, which is the aviation authority 
for Canada, has issued Canadian Airworthiness Directive CF-2014-25, 
dated August 7, 2014 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model BD-700-1A10 and BD-
700-1A11 airplanes. The MCAI states:

    There have been two reports of fluid entry and accumulation in 
the aft equipment bay. The leaked fluid in the first incident was 
fuel and the fluid in the second incident was test dye. Further 
investigation revealed that leaked fluid from the aft fuel tank 
drain entered the bay through the slot in the door latch mechanism.
    Flammable fluid entry and accumulation in the aft equipment bay, 
in excessive quantities, could exceed safe levels maintained by the 
drainage and ventilation system.
    Bombardier Inc. has issued several Service Bulletins (SB) to 
modify the Aft Equipment Bay by installing a cover to the door latch 
mechanism in order to reduce the risk of fuel entry into it. This 
[Canadian] AD mandates the incorporation of the applicable 
Bombardier Inc. SBs to rectify this problem.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
0081.

Related Service Information

    Bombardier has issued the following service information:
     Bombardier Service Bulletin 700-1A11-52-019, dated March 
29, 2012.
     Bombardier Service Bulletin 700-52-042, dated March 29, 
2012.
     Bombardier Service Bulletin 700-52-5007, dated March 29, 
2012.
     Bombardier Service Bulletin 700-52-6007, dated March 29, 
2012.
    The service information describes procedures for the modification 
of the aft equipment compartment door. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

[[Page 3925]]

Costs of Compliance

    We estimate that this proposed AD affects 60 airplanes of U.S. 
registry.
    We also estimate that it would take about 8 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about 720 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $84,000, or $1,400 per product.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, New York ACO, 
ANE-170, FAA; or Transport Canada Civil Aviation (TCCA); or 
Bombardier, Inc.'s TCCA Design Approval Organization (DAO). If 
approved by the DAO, the approval must include the DAO-authorized
